Description
The TSV912H and TSV912AH operational
amplifiers offer low voltage operation and rail-torail input and output.
The devices feature an excellent speed/power
consumption ratio, offering an 8 MHz gainbandwidth product while consuming only 1.1 mA
maximum at 5 V. They are unity gain stable and
feature an ultra-low input bias current.
The TSV912H is a high temperature version of
the TSV912, and can operate from -40°C to
+150°C with unique characteristics. Its main
target applications are automotive, but the device
is also ideal for sensor interfaces, batterysupplied and portable applications, as well as
active filtering.

7. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.
8. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of
connected pin combinations while the other pins are floating.
9. Charged device model: all pins and the package are charged together to the specified voltage and then
discharged directly to the ground through only one pin. This is done for all pins.

TSV912H, TSV912AH Application information
3 Application information
3.1 Driving resistive and capacitive loads
These products are low-voltage, low-power operational amplifiers optimized to drive rather
large resistive loads above 2 kΩ.
In a follower configuration, these operational amplifiers can drive capacitive loads up to
100 pF with no oscillations. When driving larger capacitive loads, adding a small in-series
resistor at the output can improve the stability of the devices (see Figure 18 for
recommended in-series resistor values). Once the in-series resistor value has been
selected, the stability of the circuit should be tested on bench and simulated with the
simulation model.
Figure 18. In-series resistor vs. capacitive load
3.2 PCB layouts
For correct operation, it is advised to add 10 nF decoupling capacitors as close as possible
to the power supply pins.
